What will I learn?

This API Testing Course teaches you how to build strong Postman collections, set clear API agreements, and check JSON setups, status codes, and authentication processes for a Book Store REST API. You will make automated tests using Newman, connect them to continuous integration, manage secrets securely, use mock servers well, and provide repeatable, well-explained test plans that reviewers can rely on and teams can run without worry.

What our students say

Your classes are perfect. I purchased the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... I appreciate everything you do, I've already recommended you to others...
